Specification of-Letters Patent; Patented N 28 1911 Application filed February 13,1911. Serial No. 608,471.

- To all whom mega} concern:

. 'Be it that I, HOWARD MEAD, a

citizen of the United States of America,

and residen t of the city of St. Louis, Misso'uri, have invented a certain new and usef ful Improvement in Box-Blank Machines,

i of which the-following is a specification.

f My invention relates to machines for making the b'lanks from which wire bound boxes It relates more-particularly to" machines.

"of this kind"inwhich an endless traveling work-holder is employed, such, for example, as themachineshown in United States Letters Patent- Number 864,955 granted to E. Craig, 'VVillia-In 'P. Healey, assignee, Septem'bera3, 1907, for improvement 1n box blank machines. In a machine of this kind,

' as described "in said patent, provision is made [for making blanks of different vlengths. This is done, it will be,understood,

by varying'the distance between the spacing I block s'on the endless traveling work-holder.

\Vhehthis is done, it frequently happens that the measuring off of the distance clear I around-the work-holder does not come out I evenkln' other Words, there will be a space left which is. tooshort for the length of blank being made.- In such case,and prior to my invention, a waste of wire will occur when the wires are made to jump the said space, if the machine be operated continuously. In time this waste of wire willbe considerable, and would increase the cost of production ofthe boxes. Such waste of wire can, of course, be overcome by taking "out 'ajfew links of the chain, as this will 'elimin'a'tethe old space. I This, however,

takes some time, and it has been found that theusers of" this kind of machinery prefer to'keep the chain or. link belt work-holder thesame in length for different lengths of work-holder.

blank; In'Other words, they prefer to lose by "wasting the wire in, jumping the odd space, thanto consume the time necessary to takeout some of the links of the traveling At least, this is the method "followed by'some users of this machine.

/ Theobject of my invention" is, therefore,

toprovide an arrangement whereby blanks 'of different lengths can be made on a machine of'this' kind, Withoutthe necessity of taking out and" put-ting back any links of the endless traveling 'work ho1der,

land claimed of the and without wasting the wire in the manner previously stated.

To this and other useful ends, my invention consistsin' matters hereinaftelr set forth In-the accompanying drawings-{ igure 1 is a longitudinal section of a machine for making box blanks, which machine is of the kind shown in the previously mentioned Letters Patent, showing my improvement applied thereto. Fig. 2 is a perspective of one of the devices constituting my improvement, which devices are arranged immediately back of the staplers of the said machine, and immediately over the binding wires at the point where the blanks and wires pass out from under the staplers, whereby each blank must pass under these devices before being delivered from the machine. Fig. '3 is aperspective illustrating the manner in which the said devices of my improvement are mounted on a rod which extends transversely of the machine, as well as the way in which the said devices are 'e'achdisposed over the path of travel of one of the binding wires, the illustration also including in perspective a portion of one of the box blanks.

As thus illustrated, the machine comprises the endless traveling work-holder A, the

staplers B, and the feed mechanism C for said work-holder, which instrum'entalities are, as indicated, of exactly the same construction as those shown in the previously mentioned Letters Patent. The said workholder is, therefore, provided with spacing blocks of the kind shown in said Letters Patent, of any suitable character, for spacing the cleats of the blanks apart endwise, in the usual and well known manner. These spacing blocks are adjustable upon the chains of the work-holder, in the manner described in said. Letters Patent, with respectto cleats of different lengths, whereby the length of the box-blanks can be varied at will. For some lengths of blank, how

ever, the measuring off of the work-holder in this manner does not come out even and it frequently happens that an odd space is left which cannot' be used, as it is too short for a blank, or too short for a complete section of a blank. In such case it is obvious, if the machine be run continuously, that a considerable waste of wire will occur, as it lower endv of the-said arm, which prongs along will be compelled to jump the said space, and when the blanks are cut apart the wire where it w s forced to jump the space will have to be lzut out and thrown away. This is the result, assuming, of course, that no links are taken out of or put into the workholder, in order to correctthe difiiculty. As prev ously explained, the average user, for various reasons, will-prefer to let the wire jum the vacant space, and will not take the tron le to change the length of the workholder. With a view, therefore, to correct- ;ing this diflicult I provide .the. machine with the'devices l) wh ch afford the opportunity for a new mode of operation of the machine, as follows :v Each 4 device consists of an 'arm d which is adjustably mounted upon a-rod d that crosses the machine im mediatel back-of the sta lers, above the work-holder, and of a pair of prongs d at the provide a V -shaped-opening between them. t will be seen that these V-shaped 0 enings or notches; are directly over the inding wires-E of the wire-bound boxblank F, as shown in Fig. 3 butthe said prongs (1 do .not hang down low enough to quite touch the upper surface of the blanks as they travel of a certain length, by adjustingthe spacing blocks thereon, and after so doing an odd space. isleft over which cannot be used. .In such case, and just as the said space hegins to emerge or pass out from under the next blank and begin to feed again, and

with the result that no Wire is wasted between the twoblanks. The attendant will do this each time the odd or vacant space comes around, or any other arrangement can be employed for raising the-blank, and

thusno waste of wire is caused by the latter being compelled to jump orvstretch over a s acebetween two blanks which'is greater than is ordinarily necessary for insuring wire end portions of. suitable length for twistin together when the blanks are converted into boxesthat is to say, for twist- .ing together to close the covers of the boxes in the usual and well known manner. This, however, and without, some provision to the contrary, cannot be done without disarranging the wires, or without danger'ofso doing,

and if they aredisarranged there will then be trouble when the attendant allows the ch angin elow. Now, suppose that the'work-. holder has. been measured off for. a blank blank to drop back onto the work-holder or staplers for engaging and holding the wires in place. It is for this reason, therefore, that the devices D are provided, as they serve to engage the wires and hold themin place while the blank is bein held up, and insure the proper stapling o the wires to the next blank as soon as it comes along and catches up with the one ahead which has been raised for that'purpose. In this way, the machine can be adjusted for blanks of different lengths, without the necessity of the length of the chains of the work-ho der, and without wasting the wire when a space is left over which cannot be used By myinvention, therefore, I make it possible to employa new mode of operaeling work-holder having the circumference thereof spaced or divided for blanks of a certain length, there being an odd space .left over which cannot be used and which remains vacant, and means behind the staplers for engaging and holding the bindin wires against disarrangement when the blank ahead of said space islifted out of engagement with the work-holder to allow the blank behind to catch up. 7
